I am receiving two multiple errors on my blog homepage.

Warning: date(): It is not safe to rely on the system's timezone settings. You are required to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home2/highasa1/public_html/thecoloursofblack.com/blogs/inc/sessions/model/_session.class.php on line 226

I noted that there was previous issues with this and the solution then was to add the line <date.timezone = "America/New_York"> to the php.ini. This I have done and the results are the same.

I have also added the line <SetEnv TZ America/New_York> to my .htaccess file but I still have the error messages.

My blog can be found at "http://thecoloursofblack.com/blogs/mattblack.php" - I am unsure of the actual version of b2evolution that is installed on my system as I am unable to log into the dashboard. I have scanned through the .php files but cannot find a version number.
